"Hello, the new galactic governor." Out of etiquette, Zhang Yuan replied politely.

He couldn't help sighing. As mankind bravely took that step, the two sides seemed to be on the same level and could talk equally.

Zhang Yuan now knows that there are not many civilizations that are willing to manage the galaxy. Most of the five level civilizations, or even more advanced civilizations, have their own ideals and plans, and are not willing to spend a lot of time on the endless degenerate civilizations

"We are here to invite you to join us."

Alev civilization introduced a very huge plan: they wanted to make the whole galaxy, every planet with intelligent life, into a standard intelligent unit.

“…… Then these standard units are connected in series through the superluminal network system to form a galaxy level Gaia creature

"Yes, Gaia, have you ever heard of it? It's a kind of swarm intelligence. The intelligence level of this kind of group life will increase with the increase of the number of species. "

"Every different intelligent creature will provide Gaia with its own intelligence, and then turn it into a whole."

The ultimate goal of Noah's faction is to connect the whole universe and create a cosmic group of creatures - Noah!

"How intelligent this creature will be! At present, Noah's level of wisdom is already level nine civilization! Her potential is still growing. "

"If your civilization is willing to participate in this great cause, we would be very grateful. Our single civilization is too weak. Even a small galaxy will take us tens of thousands of years. "

In the face of such a huge object, Zhang Yuan suppressed the shock in his heart and asked: "however, once this is done, if all the low-level civilizations are assimilated, won't it be very difficult to create a new five level civilization?"

"Yes, it is. But you have to know that most of the civilizations in the universe are degenerates. They no longer have room for progress. They have no ideals of their own and do not explore the meaning of life. Isn't it more meaningful to assimilate them and become a part of Noah? And we don't mind excluding them from the plan when we encounter a class IV civilization with great potential As a ninth level civilization, Noah does not have many more intelligent units, nor does he lack one. "

Zhang Yuan also asked: "occupying a large number of sites, other civilizations have been compressed living space, won't you just sit back and watch?"

Alev civilization is very domineering said: "according to the information known at present, the high-level civilization with contrary ideas is not as strong as us. As for the other nine civilizations Or even greater civilizations, with their own goals, who can understand what we are doing. "

"And a stronger civilization?"

"There is, of course. And under normal circumstances, we don't occupy the whole universe, like the big Magellanic Galaxy next door. We just assimilate some degenerates. "

Alev civilization left after expounding his ideas, leaving only Zhang Yuan in a daze

Will human beings stop this crazy civilization? Not really.

And humans have jumped out of the chessboard, from pieces to players. It seems that alev civilization will not take the initiative to attack mankind.

In fact, if superhuman is really promoted to level five civilization, there is no problem to protect the fallen earth people.

For the Noah faction, there is no big difference between one more or one less standard intelligence unit, just like a cell in the human body. It doesn't matter whether one is dead or alive, or even can't feel it.

Alev civilization will not encounter with a five level civilization because of such a small matter, which will only waste its time for no reason.

However, with so much information, Zhang Yuan's mentality has changed miraculously

The sky that human beings have seen before is really too small. It is always tangled with some trivial matters. Now, after receiving this series of invitation, it's like a frog from the bottom of the well jumps out of the well, and the sky you see expands countless times!

Next, the ball of light actually lit up again. A faction named engineer invited him.

The engineer said ambitiously, "we want to know the shape of the universe! That's our goal! This shape refers to the abstract description of mathematics! We've designed so many experiments that you'll be interested in! "

"The universe is high latitude, even if it is a very powerful civilization, it is difficult to see the whole picture of the universe, so what is the shape of the universe? Is it a saddle shape, a swimming circle shape, or a ball shape? "

"For this reason, we have designed some special methods..."

Zhang Yuan roughly understood the meaning of "engineer".

Measurement.

They're measuring the universe with super technology!Let's take a simple example: Galileo, the great navigator, proved that the earth is a sphere by sailing around the world.

In fact, the proof is not rigorous.

Being able to travel around the world means that the earth may be a ball, but it may also be in the shape of a swimming circle. After all, the shape of the swimming circle is also able to travel around the world.

So how to exclude this option? The famous Pang Jialai conjecture (theorem) can exclude this point.

For example, put a rubber ring on a ball, and then slowly shrink the rubber ring upward. The rubber ring will shrink to a point at the pole of the ball;

but if you put a rubber ring on a swimming ring, no matter how you move it to shrink, it will not shrink to a point.

Mathematical language: any simply connected, closed three-dimensional manifold must be homeomorphic to a three-dimensional sphere. This theorem is also true for high dimensional space.

The tools used by "engineers" are similar mathematics and super strong scientific and technological strength.

According to what the engineers just described, they are responsible for the giant power source.

“…… If you have observed the giant gravitation source, you can know that it is the special experiment that we initiated in order to measure the shape of the universe, in which we also used the natural vein of the universe, the cosmic string. However, there is no real conclusion on this aspect of research, and there are several different views. "

"If you are interested in this, you can consider joining us."

With these words, the ball of light represented by the engineer left, leaving only Zhang Yuan to stay where he was and savor the description of this super civilization.

It's incredible.

Zhang Yuan was very excited.

"Giant gravitation source" refers to a gravitational anomaly near the center of this supercluster, which also affects galaxies hundreds of millions of light-years away!

All galaxies are redshifted. According to Harper's law, they and the earth are degenerating each other, but redshift reveals this unreasonable phenomenon. Originally, humans had no idea why this happened, but now they have a conclusion: it was the super experiment made by the "engineer" faction.
